Here's the -thing- on the whole conservation issue, in my little, narrow mind.

Some day, maybe 100 years from now, maybe more, maybe less, nobody knows for sure, but some day, oil will run out, right? I mean it is a -finite- resource, right? Nobody is making more crude, right? So, even if we all conserve and ride bikes and buy Smart Cars, even then, some day, oil will still run out.

Then what?

Shouldn't we all be thinking about that day and trying to "invent" a new fuel now? A fule we can put into our cars, or trains, or airplanes, etc? Or...should we keep doing the same old thing, and just cross our fingers and hope there's enough oil to last until -we- take the big dirt nap, and put it off for the next generation to come up with new answers?

Personally, I like electricity as "fuel". All we really need is new technology to produce it and a new battery to store it.
